HYDROCARBON-TORCH.

Specification of Letters Patent.

Patented Nov. 14, 1916.

Application filed January 19, 1916. Serial No. 72,976.

To all whom it may concern:

Be it known that I, CHRISTIAN G. FILZER, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Hydrocarbon Torches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apper tains to make and use the same, reference being had to the accompanying drawings, and to'the letters of reference marked thereon, forming part of this specification.

My invention relates to hydro-carbon torches, and particularly to that type of such torches which are adapted to generate combustive gas from kerosene oil.

The objects of the present invention are to provide means to clean the tubular passages through the generator portion of my torch, and to provide suitable means for supplying burning fluid to the starting cup.

The features of my invention will be explained and pointed out hereinafter, and are illustrated in the accompanying drawings, in which:

Figure 1, is a side elevation of a hydrocarbon torch embodying my invention. Fig. 2, is a top or plan view of the same. Fig. 3, is a vertical section of a portion of the same on the line 00-00 in Fig. 1. Fig. 4, is a front end elevation of the nozzle member of my improved torch. Fig. 5, is a longitudinal section of the same on the line yg in Fig. 4. Fig. 6, is a top or plan View of the same, with portions thereof broken away. Fig. 7 is an enlarged View of the strainer member of my invention. Fig. 8, is an end view of the same. Fig. 9, is a longitudinal, vertical section of the ball-check of my invention. Fig. 10, is a bottom View of a portion of the initial starting cup, showing the latch mechanism thereof.

In these drawings A, indicates the fuel reservoir; A, the handle thereon; B, the nozzle; B, the helically coiled pipe within the nozzle B; B", the starting-cup; C, the hinged joint, and C, the air pump, all of which are shown and described in my copending application, Serial No. 51,635, filed September 20, 1915, and form no part of the present invention.

In the present invention, the tubular passage from the reservoir A is upward through the valve-seat D, to the needle-valve D,

which is controlled by the hand-wheel D in the usual manner. Upon the-valve seat 'D, I place a ball-valve D which is provided with a stem a).

In the valve casing E, I secure a bushing E, which is provided with internal threads 6, and with a stufling-box e, of usual con struction. Within the bushing E, I place a hollow shaft E which is provided with threads which engage the internal threads 6, in the bushing E. The shaft E is provided with an internal shoulder 6 which is adapted to engage a head 03, or its equivalent, on the upper end of the stem (i, so that the ball-stem d, cannot be withdrawn out of the shaft E Within the shaft E I place an adjusting-screw E which can be raised or lowered in the shaft E so as to limit the vertical movement of the ball-stem (Z, in the hollow shaft E Upon the shaft E I place a thumb-wheel E by means of which the hollow-shaft E may be lowered through the bushing E, sufiiciently to permit the ball D to seat upon the valve-seat D, so as to act as a check-valve to prevent the backward flow of fuel oil therethrough.

If it should be desired to prevent the ball D from being raised off of its seat, the hollow shaft E can be screwed down until the end of the screw E engages the upper end of the ball-stem (Z, which will thereby prevent the ball D from leaving its seat, and it may also be desirable, as hereinafter pointed out, of unscrewing the shaft E sufficiently so that the internal shoulder 0, will lift the ball off of its seat. From the needle-valve D, the tubular passage leads through the hinged joint C, and helically coiled tube 13, to the gas-jet tube F, as shown and described in my beforementioned application. In this jet-tube F, I place a strainer, (see Figs. 7 and 8) which is composed of a stem G, having thereon a plurality of disks of screening material G, of

wire gauze or other suitable material, of sufficient diameter to fit the interior of the jet tube F, said screening material being held in place on the stem G by means of washers G which are provided with radial slots g.

The stem G, is preferably flattened at g, which flattened portion prevents the washer G from moving away from the disks of screen material. The stem G, is also provided with a head 9 to retain the screen material on the stem G. When it is desired to replace the screen material on the stem G,

the washer G is turned so that the'slot 9, will receive the flattened portion g, of the stem thereinto when the washer G can be removed, and the screen material removed as may be desired. The stem G, projects slightly out of the rear end of the jet tube, so that it may be gripped by a pair of pliers for the purpose of withdrawing the strainer from the tube.

F or closing the rear end of the jet tube F, I provide a screw plug F, which has a central longitudinal hole 7", therein to receive the projecting end of the strainer-stem G, said hole not extending entirely through the screw-plug F. The jet tube F, is provided with a jet opening 7', and with a lateral opening 7, just back of the strainer material Gr, therein. This lateral opening 7, is provided with a needle-valve H, which has a thumb wheel h, by which the same may be operated. 7

From the valve H, a tube I-I, leads into the rear portion of the nozzle shell B, so that when the valve H, is opened, combustion material will freely flow. from the jet tube I into the nozzle shell B, for the purpose of cleaning out dirt which may have lodged in the jet tube F, back of the strainer Gr: also liquid fuel may be permitted to flow out of the tube H, to supply the startingcup B Another part of my invention consists in providing a tubular connection J, (see Fig. which communicates with the front coil of the helically coiled tube 13, and leads backwardly through the tube J, needle-valve J and nipple J 3, into the nozzle shell B, so that by opening the needle valve J liquid fuel can be allowed to flow into said shell and thence into the startingcup B as desired. This will also cause any dirt in the coil B, to be washed out. I provide the needle valve J with means J*, for operating it. For cleaning the jet orifice f, in the jet tube F, I provide a short rod K, (see Fig. l) which for convenience I attach to a screw plug K, secured in the upper end of the handle A, and in the lower end of the rod K, I provide a short wire 70 of suitable size for inserting into the opening f, to clean out any dirt which may lodge therein; being placed in the handle A, for safe keeping, this cleaner is always at hand when needed. The starting-cup B shown herein, is similar to that shown in my aforementioned application, being pivoted at its rear end upon the post L, and is provided with an extinguishing plate L, also pivoted 011 said post. The front ends of the cup B and plate L, are provided with perforated ears I) and Z, said ears being provided with slots as shown in'Fig. 10. The ear I), on the cup B is counter sunk on its lower side so that when the ear 6, embraces the screw M, the counter-sink will fall down and embrace the head of said screw, and when the eX- tinguishing plate L, is closed as shown in Figs. 1 and 4, the ear .7), cannot be raised upward, and the head of the screw M, being in the counter-sink on the under side of the ear I), prevents the cup from being disengaged from the screw M. On the side of the cup B I place a weighted latch-lever N, which engages the plate L, to prevent said plate from being accidentally opened, so that when it is desired to disengage the cup ear I), from the supporting screw M, the latch lever N, must be operated and the extinguishing plate L, opened, when the front end of the starting-cup can be raised sufliciently to permit the counter-sink on the under-side of the ear I), to be disengaged from the head of the supporting screw M.

Having thus fully shown and described the improvements which constitute my present invention, what I claim asnew and desire to secure by Letters-Patent is:

1. In a device of the class described, a gasjet tube having a jet opening in the point thereof, and a lateral valve-controlled opening, and a strainer member in said jet tube between the jet opening and the lateral valve-controlled opening 2. Ina device of the class described, a torch nozzle shell, a helically coiled fuel conveying tube therein, a tubular nipple secured in said nozzle shell and a tubular valve-controlled passage leading from one of the coils of said coiled tube to said nipple, whereby fuel may be discharged into said shell from said coiled tube when desired.

, 3. In a device of the class described, a torch nozzle, a starting-cup thereunder, an extinguishing plate to cover said cup, a

common pivot supporting the rear ends of said cup and plate, a supporting post secured under the front end of said nozzle, a head thereon, a laterally slotted car on said starting-cup counter-sunk on the under. surface thereof to receive the head of said supporting post, a laterally slotted ear on said extinguishing plate adapted to engage said supporting post and prevent the ear on the starting-cup from being disengaged from said supporting post, and a weighted latch lever on said starting-cup to maintain said extinguishing plate from being accidentally opened.

In testimony whereof I aifix my signature.

CHRISTIAN G. FILZER.
